A vast number of periodicals were issued by all the different sections of the Brethren through their respective publishers. Classifying these is not an easy task as they can be grouped by section, editor, date, type (gospel, ministry), target audience (adult, children, young peoples, newly converted, etc.). Here I will just look at the most populat series, and those I have personal interest in collecting.
There is an ongoing project to make PDF scans of periodicals available online. These are hosted and viewable on a website; http://www.cw-archive.org/en. We still occasionally stumble accross a series we knew nothing about before, and also list here some series that are known of, but we have no volumes to scan yet!
Not a Brethren periodical exactly but there were many contributions by William Kelly and Samuel P. Tregelles.
"A medium of intercommunication between Christians on points of Biblical Criticism, Theological Science, Christian History, Biography, and Antiquarian research. This work is of the same size and general appearance as our old friend. Notes and (Queries, of which it is in fact an alter ego in a religioo domain. The first volume, in 374 pages,' contains twenty-eight numbers published in the course of 1854. The second volume, in 416 pages, contains thirty -one numbers published in the course of 1855. The third volume also comprises thirty-one numbers, extends to 518 pages, and appeared in 1856. A portion of vol. iv. is appended, containing the seven numbers which came out in 1857, and abruptly terminated the series in consequence of the unlooked-for decease of the excellent editor, Mr. L. H. J. Tonna." From: http://archive.org/stream/journalsacredli10cowpgoog/journalsacredli10cowpgoog_djvu.txt
Scans are available, also William Kelly's contributions can be read on STEM Publishing website.
Later just called "The Witness".
[Founded by Ross in 1870 as The Northern Evangelistic Intelligencer, the magazine changed its name to The Northern Intelligencer in 1873, later The Northern Witness in 1875, and after Ross passed the editorship to J. R. Caldwell in 1876, it became The Witness in 1887 (an overdue reflection of its broadening influence), with the editorship passing on to Henry Pickering in 1914 at a monthly circulation of 16,000. It was long regarded as the principal Brethren review worldwide, and saw its monthly circulation climb to 30,000 by 1941 at the end of Pickering’s editorship.] From http://impact59.files.wordpress.com/2010/01/donald-ross-soteriological-retrospective-dec09.pdf
The numbering is curious, as 20 volumes of the original series were issued, before in 1891 commencing the 'New Series'. After 21 volumes of the N.S., in 1912 began the 'Enlarged Series'. This only lasted two years though, before in 1914 switching back to the original numbering and that year thus being volume 44!
Volumes 1-9 issued between 1891 and 1899 then from 1900 as New Series 1.
[John Ritchie continued as editor until his home call in March 1930 after which J. Charlton Steen, another well known gospel preacher and teacher of the Scriptures who had assisted Mr Ritchie for 4 years, assumed the editorship. He was an able Bible teacher but had a short tenure as editor as he was called home in September 1931. The third editor was another gifted Bible teacher whose writings are still read. William Hoste was editor until 1938. Mr Hoste studied at Cambridge University under Handley Moule. His studies of the Word of God convinced him that such teachings as baptismal regeneration apostolic succession and episcopacy were not found in the Word of God. As a result he was baptised by immersion and received into assembly fellowship. He laboured in the UK and Europe. After the death of William Hoste, Andrew Borland of Irvine, Scotland, served as editor until 1974. He taught English at Kilwinning Academy, a post that he held from his early days until his retirement. He was the author of a number of books and in great demand as a Bible teacher in Scotland and beyond. From 1974 until 1998 the editorship carried on by a committee ... The present editor is John Grant.] See here
Medium format children's magazine; I have volumes 2,3,4,7,15 .. I do not know how long it continued.
At least 16 volumes were published. I currently have 6 volumes
Very nice magazine; Notice in volume 11 confirms that was the last one.
A sample single issue cover can be seen here https://www.amazon.com/Herald-Salvation-Illustrated-Magazine-Literature/dp/B003WM9X60/ref=olp_product_details?_encoding=UTF8&me=
There is an announcement in The Christian Week, Volume 2 (ie 1880)
There were 7 volumes issued I believe, before it was renamed 'Our Record'?
After Donald Ross's death, C.W. Ross (D R's son) took over the editorship, which then passed to T.D.W. Muir for a while, before reverting in the last year of its issue to CW Ross again who wound it up with the official notification that Assembly Annals was to continue that line of magazine work. See October 1933 issue.
Extolled 'Old Paths' around the time of the 1914 division. I'm told "Ended in rancor due to its unyielding conservatism being no longer palatable to the most of the upcoming generation of Gospel Hall brethren, whose organ is now only Truth & Tidings."
Canadian magazine of the stricter Gospel Halls.
"A monthly magazine devoted to the furtherance of Christian fellowship and testimony."
Winsor Chase was Editor by 1927.
Continuation of "Armour of Light", and itself continued by "Food for the Flock". I'm told it was "an important organ of the "Chapel" OB's.".
Towards the end of 1936, editorship transferred to LLOYD G. WALTERICK - see Vol 6, p313.
Foreign missionaries magazine, issued from same place as Light and Liberty.
"For the newly converted regardless of natural age."
I know March 1916 was issue 339.
It was founded by Henry Pickering.
This page gives some information, though maybe partly mixed up with another magazine, http://www.victorianperiodicals.com/series3/single_sample.asp?id=127826
New Series continued after 75.
