FTSE 350 Constituent Companies - Current and Historical Lists

Today I learnt where to find current and historical lists of FTSE 350 constituent companies.

First I tried the London Stock Exchange website and the Financial Times. Both have good data but not exactly what I needed today. The FTSE itself provides a current list, but for historical data you need to contact the sales team. That was no good, as I didn't want to incur a large cost.

So then I looked at BIALL's How Do I? Wiki which had an entry on the exact same thing I needed, called "FTSE indices - lists of constituent companies". From this I learnt that there is a quarterly publication called Company Guide (from Charterhouse Communications) which includes FTSE 100 and FTSE 250 companies. Hurray!

Finally I contacted City Business Library, which holds the last 3 years of Company Guide, and I was kindly informed that their neighbour, the Guildhall Library, holds even longer runs that you can photocopy from. Job done. Whether or not my enquirer will make the trip up to Guildhall is another matter...
