IGI at
www.familysearch.org is free to search and use. For Scotland is has predominantly Established Church of Scotland entries from the Old Parish Registers. It is particularly good for the post official reg. period of 1855 up to around 1874ish when it tails off (the Mormons stopped loading data on at this point for Scotland).
The search screen is very versatile, have a look around it. There are a number of search tricks to it like doing a parent search (putting details of parents names only on the r/h side to see what children show for a couple with those names for example). I found Annie's birth by simply putting Ann for first name - no surname - and then only mother's name (a good way of finding illegitimate births where the child may go on to use reputed father's name would you believe!).
There are other short cuts on it, get comfortable with it first
Be aware though that entries are either actual extract from records or submitted entries (which need to be verified elsewhere). The nature of the record shows on screen.
