The expansion of the Haish Memorial Library in DeKalb looks to be a virtual certainty now that library officials have announced their plans to seek a bank loan for the remaining $6 million.

We’ve said before that the library is a community asset that clearly is in need of expansion. It has been 40 years since the last expansion of the 19,000-square-foot building, and more space is needed for the community to be better served.

But the financing for the $24 million cost of the library’s planned expansion, which would add more than 45,000 square feet to the building, is beginning to look a bit sketchy.
