A chord library is a bit like your own personal bar

It's something that's developed over time, not something you can build overnight. Since I began playing, I would collect the tabs for songs in the "lyrics" section of iTunes. Some of them are proper tablature, and some of them are simply the chords listed above the lyrics. As I've encountered, and as people have pointed out, one of the biggest issues with being a self-taught guitarist is the very immediate ignorance you face when first finding songs to play. Oftentimes when you find a tab that consists of chords, the chords will be listed out in this format: G (320033).

Just as often though, chords aren't listed. If you use ultimate-guitar, you can often mouse over the chord and see the website's suggestion. This is fine for simple chords, A through G and some of the minor chords. When you get to more complicated chords though (often variations on F and B, the main barre chords), the site's suggestions aren't so great. And often, the fingering for these chords is not set in stone.

When you collect tabs though, you have a lot of people's opinions at your fingertips. One person might list a Dsus4 chord, which may be used but not tabbed out in another song. There are also plenty of variations on these types of chords (Xsus and Xadd type chords). Don't ask me what these mean; I just know how to play them.

On a new page (Chord Library) I'll list the information in my chord book, as well as my own chord library, developed over almost two years of collecting tabs. Don't be surprised if you see multiple or repeated fingerings, and don't be afraid to try these variations in the same song. Some variations sound better than the suggested chords. And aside from that, you can sometimes substitute things like Cadd9 (032033) for G (320033), and they sound basically the same. Conversely, you can insert a Cadd9 into a line that's supposedly all G, in order to make it sound more interesting. But I suppose that's a demo video for another post.
