People in the eighteenth century believed that they were living in a crime-ridden society. In addition to Capt. Alexander Smith’s and Capt. Charles Johnson’s criminal biographies, the Proceedings of the Old Bailey, and The Ordinary of Newgate’s Account, a series of books were printed in London entitled The Newgate Calendar.
There is no single authoritative text of The Newgate Calendar as there have been many versions of works bearing the name since the eighteenth century, so a brief history is offered here. Newgate Calendars were named after the infamous London gaol, Newgate, which was first built in 1188, and subjected to numerous renovations and rebuilds in its history until its demolition in 1904.
There were various criminal ‘calendars’ compiled from the beginning of the eighteenth century, such as The Tyburn Calendar, or the Malefactors’ Bloody Register (1705), and The Chronicle of Tyburn; or, Villainy Displayed in all its Branches (1720).
The first publication that bore the name of The Newgate Calendar appeared in 1774, entitled The Newgate Calendar, or the Malefactors’ Bloody Register, and published in five volumes. Five years later, there was The Malefactors’ Register; or, The Newgate and Tyburn Calendar, dedicated to the magistrate, Sir John Fielding (1721-1780), the co-founder of the Bow Street Runners, London’s first dedicated law enforcement agency.
Another publication, The New and Complete Newgate Calendar appeared in 1795, whilst William Jackson’s The New and Complete Newgate Calendar; or, the Malefactor’s Universal Register, appeared in 1818.
Like Johnson’s Lives of the Highwaymen (1734), the eighteenth-century version of The Newgate Calendar contains biographies of the most notorious criminals. For its sources, the various versions often directly plagiarised contemporary criminal narratives, in particular the ‘Last Dying Speech’ broadsides which contained news of convicted felons. In the words of the 1784 edition, The Newgate Calendar comprises:
All the most material passages in the SESSIONS PAPERS, for a long series of years; together with the Ordinary of Newgate’s Account of the Capital Convicts, and complete narratives of all the most remarkable trials. 
And some familiar faces appear in the pages of The Newgate Calendar such as Jack Sheppard (1702-1734), Jonathan Wild (1682-1725), and Dick Turpin (1705-1739). The claim to provide ‘complete’ and ‘true’ accounts of all the trials of these offenders, however, is a little suspect. Despite the claims of the Proceedings (upon which, as we have seen, The Newgate Calendar was based), for instance, to provide a ‘fair, true and perfect narrative’ the publishers of these works had the final say in their content, and they had to be entertaining so they could be profitable. Hence ‘greater attention [was] paid to murders, robberies, and thefts from the person (involving titillating details of prostitutes’ interactions with their clients)’ in order to ‘make the Proceedings appeal to a wide audience,’ and thereby proving profitable.
(For a discussion of how ‘true’ their accounts are, bear in mind that some of these authors thought that Sir John Flastaff was a real person…)
The accounts of each offender, like the broadsides and criminal biographies that they were taken from, were very formulaic in style. They begin with an account of the offender’s birth and parentage, and then describe his/her descent into a life of sin and depravity. Crime, if you have read some of the other posts on this site, in the eighteenth century was viewed as a sin. Criminals were not necessarily inherently wicked: they were people with a tragic fatal flaw in their character, which is why a lot of criminals are portrayed sympathetically in the accounts (murderers apart).  Hence in the case of the burglar Luke Cannon, it was ‘an early attachment to bad company, an early introduction to the paths of vice, [that] led with rapid success to his ruin’. 
At the close of the narrative they are hanged for their crimes.  In a world that lacked a professional police force, one of the aims of the eighteenth-century version of The Newgate Calendar was (as well as providing sensational entertainment), to function as moralist texts. Readers were supposed to shun the examples of sin and vice and avoid making the same unhappy mistakes that had led the criminals to the gallows.
In fact, the title page of the 1795 edition contains a short piece of verse which is illustrative of its aims:
The crimes related here art great and true,
The subjects vary, and the work is new,
By reading, learn the ways of sin to shun,
Be timely taught, and you’ll not be undone. 
It might be supposed that The Newgate Calendar was cheap entertainment for eighteenth-century readers. However, this is not the case: firstly, all editions of The Newgate Calendar were multivolume sets, and accompanied with fine engravings. Although we do not know the prices for the individual editions of The Newgate Calendar, comparisons can be made with the prices of other works. Volume three of Alexander Smith’s Lives of the Highwaymen (1719) cost half a crown, an expensive amount in the 1700s. Similarly, Charles Johnson’s Highwaymen addressed ‘gentlemen’. We are talking about a literate and sophisticated audience who read these books.
There were further publications bearing the name of The Newgate Calendar during the nineteenth and twentieth centuries. A major early nineteenth-century version was edited by two layers, Andrew Knapp and William Baldwin, in 1824, and given the name The Newgate Calendar; Comprising Interesting Memoirs of the Most Notorious Characters Who Have Been Convicted of Outrages upon the Laws of England since the Eighteenth Century, with a revised edition appearing in 1826.
After Knapp and Baldwin’s editions followed G. Thompson’s Newgate Calendar of 1840, which at first glance appears to be a virtual plagiarism of Knapp and Baldwin’s version. The penny dreadful version, The New Newgate Calendar, was then published weekly between 1863 and 1865, and then Camden Pelham published, in two volumes The Chronicles of Crime; or, the New Newgate Calendar in 1887.
The last large-scale five volume compilation of The Newgate Calendar was printed by the Navarre Society in 1927, whilst the Folio Society has more recently reprinted a selection of the most famous trials in two volumes, The Newgate Calendar, and The New Newgate Calendar (1951).
The legacy of The Newgate Calendar can be seen in any bookshop today. This publication, along with criminal biographies, initiated the whole ‘true crime’ book industry.
More importantly, however, criminal biographies and The Newgate Calendar paved the way for a form of literature that we still read today: the novel. Whereas fiction before the eighteenth century tended to focus upon the lives of aristocrats, such as Don Quixote (2 Vols. 1605, 1611), criminal biography primed readers for reading about ‘real life’. Hence it is no surprise that the first English novelist, Daniel Defoe (1660-1731), often made the protagonists of his novels, not Kings and nobles, but those from low life: prostitutes (Moll Flanders, 1722), pirates (Captain Singleton, 1720).
Thus although nobody today prints accounts of criminals in the same way as the publishers of The Newgate Calendar did, it has to be remembered that there would be no novels were it not for eighteenth-century criminal accounts.
