なお、「図書館と情報」の関わりが深いことに鑑みて、図書館と情報を一体的に扱う図書館情報学（としょかんじょうほうがく、英語：library and information science）という学問もある。図書館学と図書館情報学の間には、諸研究の編成体系・分野区分などに若干の違いがあるとも考えられているが、両学問ともに図書館に大きくかかわる学問であり、両学問の性質は似通っているとも考えられている。

I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
