It was a party fit for a 90th birthday, with music, a special guest and of course lots of cake.But the Arlington Public Library — the subject of the festivities Saturday morning at the Central Library downtown — couldn’t make a wish and blow out the candles.The party kicked off the library system’s ninth decade of existence, an observation with a theme of “90 Years in 90 Days.”Visitors to the main library and branches across the city can view artifacts that comprise a historical timeline of the library. The library website, www.arlingtonlibrary.org, will have interactive content on the subject, including a blog called “90 Years of Groundbreaking Reads” and a page called “90 Great Things About the Arlington Public Library.”The library system’s milestone comes as officials continue to study what to do with the aging, outdated and too small Charles W. Hawkes Central Library, at 101 E. Abram St.Residents who participated in surveys and public meetings about two years ago said they desired cozy reading areas, larger genealogy and local history collections, and high-tech community rooms where groups can gather for meetings, performances or classes. They also want a place to bring their children for activities, to meet friends, and to work on projects.Library officials say the 63,000-square-foot building near City Hall is too small to accommodate those needs. It also has a leaky roof, handicapped-access issues, electrical, plumbing and elevator problems, and a shortage of public restrooms.But any project is probably at least a few years away. Last fall, a City Council committee directed library staffers to explore how a public-private development downtown might facilitate the construction of a new Central Library, city Libraries Director Cary Siegfried said Frday.“When there is something definite in the works, we'll be shouting the news from the rooftop,” she said, “but nothing is certain at this very moment.”Take ‘N’ BakePantego’s economic development efforts continue to pay off. The latest development was the grand opening last weekend of a Papa Murphy’s Take ‘N’ Bake Pizza franchise.The store at 1607 S. Bowen Road is owned by Alex Overcash and Angelo Chantilis, business partners of Denise Barnett, who opened her second Papa Murphy’s location over the weekend as well. That store is at 4614 SW Loop 820 in Fort Worth. Her first store opened in 2008 in Saginaw.“There’s nothing like the quality of Papa Murphy’s Pizza, and our customers are very loyal,” Overcash said in a news release.
