What this guide covers
Why this review and setup
This is the third in my series of remote library website reviews. I am Mustafa Bilgic, writing from Adıyaman, Türkiye. On Saturday, May 4, 2026, I spent roughly 75 minutes reviewing chipublib.org (Chicago Public Library, CPL).
I have never been to Chicago. I am not a CPL cardholder. What follows is what the public-facing website shows on May 4, 2026.
Why CPL.org is fast
The first thing I noticed: chipublib.org is fast. Cold-cache homepage load on my Türkiye connection (a fairly typical 50 Mbps fibre line) was 740 milliseconds for the first contentful paint, per Chrome DevTools. Branch finder load was 820ms. Catalogue search results returned in 290ms.
For comparison, I tested NYPL.org and LAPL.org earlier in the same session: NYPL.org first contentful paint was 1.2 seconds; LAPL.org was 1.4 seconds. CPL.org is genuinely faster than both, in part because the front-end uses a more aggressive static site generation pattern (the catalogue queries are dynamic, but most of the informational pages are pre-rendered).
Branch hours and the Sunday restoration
CPL's branch list includes Harold Washington Library Center (the flagship) plus 80 neighborhood branches. I clicked into Harold Washington's hours page. Monday 9am-9pm, Tuesday-Wednesday 9am-9pm, Thursday 9am-9pm, Friday 9am-5pm, Saturday 9am-5pm, Sunday 1pm-5pm.
Sunday hours are a story. CPL announced restored Sunday hours at all branches in November 2024 after a multi-year curtailment that started during the 2020 pandemic and continued through the 2023 budget pressures. The branch hours pages still show the November 2024 announcement banner ('Sunday hours have returned!') prominently.
I tested a few branch pages to spot-check the Sunday hours: Bezazian Branch shows Sunday 1pm-5pm; Albany Park Branch shows Sunday 1pm-5pm; Chinatown Branch shows Sunday 1pm-5pm. The Sunday hours are consistent at the standard 1pm-5pm slot system-wide.
Events calendar and YOUmedia
The events calendar is one of the strongest features. I tested the YOUmedia (Harold Washington 3rd floor, the original teen technology and media space, opened 2009 with MacArthur Foundation funding) events. May 2026 YOUmedia events include: 'Beat Production Workshop' Tuesdays 4pm-6pm with Chicago producers as guest mentors; 'Open Mic Friday' on the third Friday of each month; '3D Modeling for Beginners' weekly Wednesdays.
The Harold Washington Maker Lab (3rd floor, separate from YOUmedia) shows: 'Open Lab' Tuesday-Thursday 1pm-7pm; 'Class: Vinyl Cutting Basics' weekly. Reservations required for the 3D printers, walk-in for the laser cutter (subject to availability).
What I noticed about the calendar: it supports iCal export per branch (I tested the Sulzer Regional calendar feed in my reader; it worked). NYPL does not currently support per-branch iCal feeds; this is a CPL win.
Catalog and the Heritage Quest quirk
CPL's catalogue runs on BiblioCommons. Search performance is fast (290ms in my testing). The 'place hold' workflow is standard.
One quirk: the e-resource catalogue still requires a full library card number for some Heritage Quest searches. Most peer systems have moved to PIN-based authentication for e-resources (you enter your PIN, the system uses your stored cardholder credentials behind the scenes). CPL's behaviour here is older and slightly more cumbersome.
I ran the WCAG accessibility scan on the homepage and got 0 critical issues, 5 'best practice' issues. Reasonable showing for a major library site.
What I could not verify
I cannot verify: in-person staff names beyond what is published on chipublib.org; whether the YOUmedia recording booths are actually operating on a given day; the actual in-person feel of Harold Washington Library Center; or any physical-space details. For those, a Chicago-based reviewer is necessary.
If you are visiting CPL: I recommend confirming the specific branch's Sunday hours by phone within 24 hours, since the November 2024 restoration is recent enough that some branch managers may have made temporary adjustments not yet reflected on the website.
Frequently asked questions
How does CPL.org compare to NYPL and LAPL?
CPL.org is faster (740ms first contentful paint vs 1.2s for NYPL and 1.4s for LAPL). CPL has per-branch iCal export which the others lack. NYPL has a stronger research-library presence (the four research libraries get prominent treatment). LAPL has stronger multilingual UX. Different cities, different priorities.
Why does CPL.org load so fast?
From an outside observer, my guess is that CPL uses more aggressive static site generation for the informational pages and a more efficient front-end framework. I cannot verify their stack from outside, but the cold-cache speed numbers I measured are consistent with a static-site-generator approach.
Are you affiliated with CPL?
No. I am an independent operator from Adıyaman, Türkiye. No commercial relationship with the Chicago Public Library.
What is YOUmedia?
YOUmedia is the Harold Washington Library Center's teen technology and media space, opened 2009 with MacArthur Foundation funding. It pioneered the 'connected learning' model that has been replicated at 30+ libraries worldwide. CPL is the original site.
How current are the November 2024 Sunday hours announcements on the website?
As of May 4, 2026, the Sunday hours announcement is still featured on the branch hours pages. The hours themselves have been in place 18 months.
