This sentence is contradicted by San Marino's current municipal code. Section 02.02.01 states: "Commencing in November, 2022, elections of members to the city council shall be held on the first Tuesday after the first Monday in November of each even-numbered year, rather than on the first Tuesday after the first Monday in November of each odd-numbered year."

So the article's statement that council elections are held in odd-numbered years is out of date and incorrect. The same code section also confirms the staggered rotation of two seats and three seats, but the election year parity changed to even-numbered years.

San Marino's official Mayor & City Council page currently identifies the council leadership as:

• Tony Chou — Mayor
• Calvin Lo — Vice Mayor
• Hunter Chang — Council Member
• John Chou — Council Member
• Gretchen Shepherd Romey — Council Member

That directly contradicts the article's statement that Gretchen Shepherd Romey is the current mayor. This appears to reflect a past 2025 council reorganization rather than the current officeholders.

The City of San Marino's official Mayor & City Council page currently lists Calvin Lo as Vice Mayor and Tony Chou as Mayor. That means the article's statement naming Tony Chou as the current vice mayor is no longer accurate.

Because the page also lists Gretchen Shepherd Romey as a council member, the article's entire "current city council members" block appears to reflect an older council lineup.

The article gives a specific present-tense inventory for The Huntington's library, but The Huntington's own current organization page lists different figures.

According to The Huntington, the library now has some 12 million items, including:

• 9.2 million manuscripts
• 437,000 rare books
• 450,000+ reference books
• 915,000 prints and ephemera
• 805,000 photographs
• 512,000 digital files

That directly conflicts with the article's older numbers (8 million manuscripts, 440,000 rare books, 777,000 photographs, 300,000 digital files, etc.). Because the article states these counts in the present tense, the figures are materially outdated.

This statement is contradicted by U.S. Census sources.

First, the Census Bureau's own geographic history explains that the category now called a census-designated place (CDP) did not exist in 1920. The Bureau says unincorporated places were first officially identified in 1950, and the term "census designated place" was adopted in 1980.

Second, the 1920 Census table for California lists "San Marino city" under incorporated places, confirming that San Marino was counted as a city, not a CDP, in that census.

So the article's claim that San Marino first appeared as a census-designated place in the 1920 census is historically wrong on both the classification and the timing.
