The IGS library collects California local planning documents in print and online (when available). Use the LPD database to search by year, jurisdiction, and type of plan.
Documents in print date back to 1955; online versions for some jurisdictions begin in 1985.
If a document is available online, the database will display its link. To access a print copy, fill out a paging slip with the document's call number and title, and bring it to the Information desk in the reading room to be paged.
