F&M Trust Monday pledged up to $50,000 over a five-year period to Bosler Memorial Library’s capital campaign for building renovations and expansion.

The bank made an initial $10,000 commitment and pledge to make $10,000 contributions over the next four years as campaign pledges and contributions reach certain levels. The library’s $6.5 million Building a Better Bosler capital campaign, which kicked off in 2010, includes a new two-story South Wing, improvements to technology, expansion of the Children’s Library, a new community meeting room, renovation of the East Wing and restoration of the stained glass window.
