Chicago’s library system publishes its 2026 year in five branch-level ledgers — visitors, circulation, computer sessions, holds placed, holds filled — plus a sixth file, WiFi, kept citywide by month. Read together they describe one system from six angles — and the sharpest fact in the set sits inside a single one of them: most of what the circulation ledger counts is recorded on lines that are not branches. Of 8,099,853 circulation items through July, 6,261,667 — 77.3 percent — sit on five such lines: Auto-Renewals (3,464,617, nearly double all 82 branch lines combined), Downloadable Media, two patron renewal channels, and Talking Book and Braille downloadables. Meanwhile the buildings counted 4,939,899 visitors through August, led by Harold Washington — with a label new to the visitors file already third.
Six Chicago Public Library 2026 files read whole as retrieved September 10, 2026, each summed to its own through-month (visitors and computer sessions through August; circulation and holds through July; WiFi, filed system-wide by month this year, through July) · year-over-year comparisons live in this site’s earlier library pieces, linked below — this page reads 2026 alone · visits and sessions are counted events, not people, and no figure here is a count of personsThis is the multi-ledger read — the visits story lives elsewhere
Keep Chicagoland Moving has read the library’s books twice before: the 2019-to-2025 visits arc and the 2025 branch ranking. Both were one measure followed across years. This page flips that: one year, every measure — and the files do not even agree on conventions. The five location-level files carry 82, 87, 82, 84 and 82 rows (counts that include their non-branch system lines); the holds files write branch names in capitals; the two Daley-named branches are spelled three different ways across files; and the sixth file, WiFi, which earlier years published by location, files 2026 as twelve system-wide monthly rows. So this page reads each file as filed and joins nothing.
The circulation ledger’s biggest lines are not buildings
| Circulation line (through July) | Items |
|---|---|
| Auto-Renewals | 3,464,617 |
| Downloadable Media | 2,588,132 |
| Patron Initiated renewals (online) | 176,724 |
| Patron Initiated renewals (automated phone) | 0 |
| Talking Book and Braille downloadable | 32,194 |
| All five system lines | 6,261,667 |
| All 82 branch lines, combined | 1,838,186 |
Read against each other, the lines rearrange where the ledger’s weight sits. The Auto-Renewals line alone, at 3,464,617, is 1.9 times the 82 branch lines combined; add the other four non-branch lines and together they hold 77.3 percent of the ledger. Among the buildings, Sulzer Regional leads with 177,397 items through July — ahead of Harold Washington, the central library. None of this is a claim about what Chicagoans read or borrow; it is a fact about how the ledger itself is kept, in the ledger’s own labels.
Holds: placed on online lines, filled on branch labels
The two holds ledgers, side by side, describe a round trip. Holds placed, through July: 3,728,777 — of which 2,588,132 sit on the Downloadable Media line, 1,089,455 on a line the file labels simply “Online,” and just 51,190 across every branch line in the file. Holds filled, through July: 694,340, and every one of them on a branch label — Sulzer Regional first at 74,442, Harold Washington at 40,095, Edgewater and Lincoln Park behind. One number deserves its own sentence: the holds-placed file’s Downloadable Media line and the circulation file’s Downloadable Media line read identically — 2,588,132 — as retrieved. This page notes the match and reconciles nothing: how the two files share that line is not stated in either.
Visitors: 4.9 million through August, and a new label in third
| Branch (visitors file label) | Visitors, Jan–Aug 2026 |
|---|---|
| Harold Washington Library Center | 669,928 |
| Sulzer Regional Library | 200,894 |
| Obama Presidential Center Branch Library | 194,354 |
| Chinatown | 164,867 |
| Bucktown-Wicker Park | 115,827 |
| Edgewater | 111,470 |
Harold Washington’s 669,928 is more than three times any other line. The entry worth a second look is third place: the Obama Presidential Center Branch Library, at 194,354 — a label that does not appear anywhere in the 2025 visitors file, a check we ran against that file directly. The 2026 ledger does not say when the branch opened or what months it operated, so this page ranks the label as filed and claims nothing about its pace. July was the system’s biggest visiting month so far — 726,534 — with August close behind at 707,026.
Computer sessions and WiFi: two digital-access measures, kept differently
The computer-sessions file counts 842,898 sessions through August, and it is the ledger where the central library towers most by multiple: Harold Washington’s 99,571 runs 2.8 times second-place Woodson Regional’s 35,310 — a different second place than any other ledger’s. The WiFi file counts 2,774,059 sessions January through July — filed citywide by month this year, so no branch can be read from it. Its own shape has one spike: April’s 583,567 sessions, half again its neighbors’ (March 390,950, May 351,167), printed here as filed with no cause on offer.
What the ledgers confirm, and what they cannot tell you
Confirmed, ledger by ledger: every count above, each verified against its file’s own year-to-date column, row by row, and each summed only to its own through-month. What no file holds: people — a visit, a session, a renewal are events, and one person can be hundreds of them; what the branch-versus-system split says about demand — an auto-renewal is the ledger’s label for an item kept longer, not a new borrowing decision, and this page draws no demand claim from it; whether the same branch is the same line across files — the spelling conventions differ, so cross-file identity is not asserted; and anything about why the WiFi file changed its grain or why April spiked. August circulation and holds are simply not filed yet as of retrieval, and every total here says which months it covers.
Where the record lives
Six files, all under the Chicago Public Library’s pages on the city portal: visitors, circulation, computer sessions, holds placed, holds filled and WiFi. Each updates monthly in season; every figure on this page recomputes from the files as retrieved September 10, 2026, and later months will move the totals.
The bottom line
Read as one 2026 report, the six files say: the buildings drew 4.94 million visits through August and recorded 1.84 million circulation items on branch lines through July — while the non-branch lines carried 6.26 million circulation items, 77.3 percent of that ledger, and nearly all hold-placing was recorded on the Online and Downloadable Media lines before 694,340 holds were recorded as filled on branch labels. The library the visitor ledger describes and the library the circulation ledger describes are the same system measured through different reporting lines — and the circulation ledger’s own lines say where its counting sits.
Two more questions the files can answer
Which branch fills the most holds? Sulzer Regional, 74,442 through July, with the central library second at 40,095 — one of exactly two ledgers where Sulzer’s label leads Harold Washington’s, the other being branch-line circulation (177,397 to 153,852); in visitors and computer sessions the order flips. And the biggest visiting month? July, at 726,534 across the system’s 82 lines — with March (680,957) the spring peak, as filed.
- Source: six Chicago Public Library 2026 files on the city portal (visitors gy5m-7w2w, circulation ds8a-hwvu, computer sessions uyx9-2v23, holds placed iump-vuj3, holds filled xgw6-5ftq, WiFi vvck-6u3v), each read whole as retrieved September 10, 2026.
- Grain: in the five branch-level files, one row per line with monthly columns plus a year-to-date column; every row’s YTD was verified as the sum of its filled months. The WiFi file is different: twelve rows, one per month, citywide, with a running YTD verified the same way. Every citywide figure names its through-month (August for visitors and computer sessions; July for circulation, holds and WiFi). Non-branch lines are reported under the files’ own labels.
- Not joined: no cross-file branch matching — label conventions differ across files (capitals, suffixes, three spellings of the Daley branches), so each ledger’s leaders are reported in that ledger’s own labels; the identical 2,588,132 on two files’ Downloadable Media lines is noted, not reconciled.
- Not here: no people counts, no demand claims, no year-over-year comparison (the earlier pieces linked above own that), and no explanation for the WiFi file’s new system-wide grain or its April spike — none is stated in the files.
