All scottish records are avaiable on line for a small fee.
No, that is absolutely not the case.
Scotland's People is one of the great wonders of the genealogical world - a treasure trove of original information (unlike several web sites I could but will not name that contain nuggets of genuine information swamped in oceans of irrelevant, plain wrong and multiply duplicated misinformation).
However SP includes only certain parts of the information formerly held by the Registrar General for Scotland and National Archives of Scotland, and now held by the National Records of Scotland.
There are vast repositories of information out there in various archives that are not available online:
Kirk Session records
Parochial Board (Poor Law) records
School records
Estate records (there is one estate archive that I know of which is said to consist of 2½
tons of documents
Registers of deeds
Registers of Episcopalian churches
Registers of Free and dissenting churches
Court records (civil and criminal)
Hospital and asylum records
Registers of sasines
Services of heirs
Burial records
to name but a few that I have used over the years.
However they are not as easy to access as the Scotland's People ones. Generally you have to find out that they exist (sometimes but not always possible online), go to wherever they are, and then read through what can be many pages of difficult handwriting to pick out the item that interests you.
If you strike lucky you can find real gems - I found (in the 2½ tons) a letter written in his own hand by one of my umpteenth-great-grandfathers in 1771, and a sasine taking another branch of the family back to an even-further-back-great-grandfather who died in 1642. If you don't, you can spend a day reading fruitlessly through an unindexed book of deeds, knowing that you still have three dozen more books to check.
But as Dave says it isn't easy for him to get to Glasgow or Edinburgh, none of this is readily accessible to him, unfortunately, or to anyone else in the same predicament.
