Note that library hours is one of the possible bits of information that 
could be encoded as RDFa in the library web site, thus making it 
possible to derive library hours directly from the listing of hours on 
the web site rather than keeping a separate list. does have 
the elements such that hours can be encoded. This would mean that hours 
could show in the display of the library's catalog entry on Google, 
Yahoo and Bing. Being available directly through the search engines 
might be sufficient, not necessitating creating yet-another-database for 
that data. uses a restaurant as its opening hours example, but much of 
the data would be the same for a library:

<div vocab="" typeof="Restaurant">
   <span property="name">GreatFood</span>
   <div property="aggregateRating"  typeof="AggregateRating">
     <span property="ratingValue">4</span> stars -
     based on <span property="reviewCount">250</span> reviews
   <div property="address"  typeof="PostalAddress">
     <span property="streetAddress">1901 Lemur Ave</span>
     <span property="addressLocality">Sunnyvale</span>,
     <span property="addressRegion">CA</span> <span 
   <span property="telephone">(408) 714-1489</span>
   <a property="url" href=""></a>
   <meta property="openingHours" content="Mo-Sa 11:00-14:30">Mon-Sat 
11am - 2:30pm
   <meta property="openingHours" content="Mo-Th 17:00-21:30">Mon-Thu 5pm

   <meta property="openingHours" content="Fr-Sa 17:00-22:00">Fri-Sat 5pm

   <span property="servesCuisine">
     Middle Eastern
   <span property="servesCuisine">
   Price Range: <span property="priceRange">$$</span>
   Takes Reservations: Yes

It seems to me that using would get more bang for the buck -- 
it would get into the search engines and could also be aggregated into 
whatever database is needed. As we've seen with OCLC, having a separate 
listing is likely to mean that the data will be out of date.
